National Trends in Psychotropic Medication Polypharmacy in Office-Based Psychiatry

CONTEXT Psychotropic medication polypharmacy is common in psychiatric outpatient settings and, in some patient groups, may have increased in recent years. OBJECTIVE To examine patterns and recent trends in psychotropic polypharmacy among visits to office-based psychiatrists. DESIGN Annual data from the 1996-2006 cross-sectional National Ambulatory Medical Care Surveys were analyzed to examine patterns and trends in psychotropic polypharmacy within nationally representative samples of 13 079 visits to office-based psychiatrists. SETTING Office-based psychiatry practices in the United States. PARTICIPANTS Outpatients with mental disorder diagnoses visiting office-based psychiatrists. MAIN OUTCOME MEASURE Number of medications prescribed in each visit and specific medication combinations. RESULTS There was an increase in the number of psychotropic medications prescribed across years; visits with 2 or more medications increased from 42.6% in 1996-1997 to 59.8% in 2005-2006; visits with 3 or more medications increased from 16.9% to 33.2% (both P < .001). The median number of medications prescribed in each visit increased from 1 in 1996-1997 to 2 in 2005-2006 (mean increase: 40.1%). The increasing trend of psychotropic polypharmacy was mostly similar across visits by different patient groups and persisted after controlling for background characteristics. Prescription for 2 or more antidepressants, antipsychotics, sedative-hypnotics, and antidepressant-antipsychotic combinations, but not other combinations, significantly increased across survey years. There was no increase in prescription of mood stabilizer combinations. In multivariate analyses, the odds of receiving 2 or more antidepressants were significantly associated with a diagnosis of major depression (odds ratio [OR], 3.44; 99% confidence interval [CI], 2.58-4.58); 2 or more antipsychotics, with schizophrenia (OR, 6.75; 99% CI, 3.52-12.92); 2 or more mood stabilizers, with bipolar disorder (OR, 15.46; 99% CI, 6.77-35.31); and 2 or more sedative-hypnotics, with anxiety disorders (OR, 2.13; 99% CI, 1.41-3.22). CONCLUSIONS There has been a recent significant increase in polypharmacy involving antidepressant and antipsychotic medications. While some of these combinations are supported by clinical trials, many are of unproven efficacy. These trends put patients at increased risk of drug-drug interactions with uncertain gains for quality of care and clinical outcomes.

Barriers to mental health treatment: results from the National Comorbidity Survey Replication.

BACKGROUND The aim was to examine barriers to initiation and continuation of treatment among individuals with common mental disorders in the US general population. METHOD Respondents in the National Comorbidity Survey Replication with common 12-month DSM-IV mood, anxiety, substance, impulse control and childhood disorders were asked about perceived need for treatment, structural barriers and attitudinal/evaluative barriers to initiation and continuation of treatment. RESULTS Low perceived need was reported by 44.8% of respondents with a disorder who did not seek treatment. Desire to handle the problem on ones own was the most common reason among respondents with perceived need both for not seeking treatment (72.6%) and for dropping out of treatment (42.2%). Attitudinal/evaluative factors were much more important than structural barriers both to initiating (97.4% v. 22.2%) and to continuing (81.9% v. 31.8%) of treatment. Reasons for not seeking treatment varied with illness severity. Low perceived need was a more common reason for not seeking treatment among individuals with mild (57.0%) than moderate (39.3%) or severe (25.9%) disorders, whereas structural and attitudinal/evaluative barriers were more common among respondents with more severe conditions. CONCLUSIONS Low perceived need and attitudinal/evaluative barriers are the major barriers to treatment seeking and staying in treatment among individuals with common mental disorders. Efforts to increase treatment seeking and reduce treatment drop-out need to take these barriers into consideration as well as to recognize that barriers differ as a function of sociodemographic and clinical characteristics.

Association between public views of mental illness and self-stigma among individuals with mental illness in 14 European countries

BACKGROUND Little is known about how the views of the public are related to self-stigma among people with mental health problems. Despite increasing activity aimed at reducing mental illness stigma, there is little evidence to guide and inform specific anti-stigma campaign development and messages to be used in mass campaigns. A better understanding of the association between public knowledge, attitudes and behaviours and the internalization of stigma among people with mental health problems is needed. METHOD This study links two large, international datasets to explore the association between public stigma in 14 European countries (Eurobarometer survey) and individual reports of self-stigma, perceived discrimination and empowerment among persons with mental illness (n=1835) residing in those countries [the Global Alliance of Mental Illness Advocacy Networks (GAMIAN) study]. RESULTS Individuals with mental illness living in countries with less stigmatizing attitudes, higher rates of help-seeking and treatment utilization and better perceived access to information had lower rates of self-stigma and perceived discrimination and those living in countries where the public felt more comfortable talking to people with mental illness had less self-stigma and felt more empowered. CONCLUSIONS Targeting the general public through mass anti-stigma interventions may lead to a virtuous cycle by disrupting the negative feedback engendered by public stigma, thereby reducing self-stigma among people with mental health problems. A combined approach involving knowledge, attitudes and behaviour is needed; mass interventions that facilitate disclosure and positive social contact may be the most effective. Improving availability of information about mental health issues and facilitating access to care and help-seeking also show promise with regard to stigma.

National Trends in Child and Adolescent Psychotropic Polypharmacy in Office-Based Practice, 1996-2007

OBJECTIVE To examine patterns and recent trends in multiclass psychotropic treatment among youth visits to office-based physicians in the United States. METHOD Annual data from the 1996-2007 National Ambulatory Medical Care Surveys were analyzed to examine patterns and trends in multiclass psychotropic treatment within a nationally representative sample of 3,466 child and adolescent visits to office-based physicians in which a psychotropic medication was prescribed. RESULTS There was an increase in the percentage of child visits in which psychotropic medications were prescribed that included at least two psychotropic classes. Across the 12 year period, multiclass psychotropic treatment rose from 14.3% of child psychotropic visits (1996-1999) to 20.2% (2004-2007) (adjusted odds ratio [AOR] = 1.89, 95% confidence interval [CI] = 1.22-2.94, p < .01). Among medical visits in which a current mental disorder was diagnosed, the percentage with multiclass psychotropic treatment increased from 22.2% (1996-1999) to 32.2% (2004-2007) (AOR = 2.23, 95% CI = 1.42-3.52, p < .001). Over time, there were significant increases in multiclass psychotropic visits in which ADHD medications, antidepressants, or antipsychotics were prescribed, and a decrease in those visits in which mood stabilizers were prescribed. There were also specific increases in co-prescription of ADHD medications and antipsychotic medications (AOR = 6.22, 95% CI = 2.82-13.70, p < .001) and co-prescription of antidepressant and antipsychotic medications (AOR = 5.77, 95% CI = 2.88-11.60, p < .001). CONCLUSIONS Although little is known about the safety and efficacy of regimens that involve concomitant use of two or more psychotropic agents for children and adolescents, multiclass psychotropic pharmacy is becoming increasingly common in outpatient practice.

National Trends in Psychotherapy by Office-Based Psychiatrists

CONTEXT In addition to prescribing medications, providing psychotherapy has long been a defining characteristic of the practice of clinical psychiatry. However, there are indications that the role of psychiatrists in providing psychotherapy may have diminished in recent years. OBJECTIVE To examine recent national trends in the provision of psychotherapy by office-based psychiatrists. DESIGN Data from the 1996 through 2005 cross-sectional National Ambulatory Medical Care Survey were analyzed to examine trends in psychotherapy provision within nationally representative samples of visits to office-based psychiatrists. Multivariate analyses examined the time trend, adjusting for patient, visit, and setting characteristics. Practice-level analyses examined time trends in the percentage of psychiatrists who provided psychotherapy to all, some, or none of their patients during a typical week. SETTING Office-based psychiatry practices in the United States. PARTICIPANTS Patients with psychiatric diagnoses visiting outpatient psychiatrists. MAIN OUTCOME MEASURE Provision of psychotherapy in visits longer than 30 minutes. RESULTS Psychotherapy was provided in 5597 of 14,108 visits (34.0% [weighted]) sampled during a 10-year period. The percentage of visits involving psychotherapy declined from 44.4% in 1996-1997 to 28.9% in 2004-2005 (P < .001). This decline coincided with changes in reimbursement, increases in managed care, and growth in the prescription of medications. At the practice level, the decrease in providing psychotherapy corresponded with a decline in the number of psychiatrists who provided psychotherapy to all of their patients from 19.1% in 1996-1997 to 10.8% in 2004-2005 (P = .001). Psychiatrists who provided psychotherapy to all of their patients relied more extensively on self-pay patients, had fewer managed-care visits, and prescribed medications in fewer of their visits compared with psychiatrists who provided psychotherapy less often. CONCLUSIONS There has been a recent significant decline in the provision of psychotherapy by psychiatrists in the United States. This trend is attributable to a decrease in the number of psychiatrists specializing in psychotherapy and a corresponding increase in those specializing in pharmacotherapy--changes that were likely motivated by financial incentives and growth in psychopharmacological treatments in recent years.

Dropout From Outpatient Mental Health Care in the United States

OBJECTIVE Although mental health treatment dropout is common, patterns and predictors of dropout are poorly understood. This study explored patterns and predictors of mental health treatment dropout in a nationally representative sample. METHODS Data were from the National Comorbidity Survey Replication, a nationally representative household survey. Respondents who had received mental health treatment in the 12 months before the interview (N=1,664) were asked about dropout, which was defined as quitting treatment before the provider wanted them to stop. Cross-tabulation and discrete-time survival analyses were used to identify predictors. RESULTS Approximately one-fifth (22%) of patients quit treatment prematurely. The highest dropout rate was from treatment received in the general medical sector (32%), and the lowest was from treatment received by psychiatrists (15%). Dropout rates were intermediate from treatment in the human services sector (20%) and among patients seen by nonpsychiatrist mental health professionals (19%). Over 70% of all dropout occurred after the first or second visits. Mental health insurance was associated with low odds of dropout (odds ratio=.6, 95% confidence interval=.4-.9). Psychiatric comorbidity was associated with a trend toward dropout. Several patient characteristics differentially predicted dropout across treatment sectors and in early and later phases of treatment. CONCLUSIONS Roughly one-fifth of adults in mental health treatment dropped out before completing the recommended course of treatment. Dropout was most common in the general medical sector and varied by patient characteristics across treatment sectors. Interventions focused on high-risk patients and sectors that have higher dropout rates will likely be required to reduce the large proportion of patients who prematurely terminate treatment.

The Mental Health Consequences of the Recession: Economic Hardship and Employment of People with Mental Health Problems in 27 European Countries.

Objectives A period of economic recession may be particularly difficult for people with mental health problems as they may be at higher risk of losing their jobs, and more competitive labour markets can also make it more difficult to find a new job. This study assesses unemployment rates among individuals with mental health problems before and during the current economic recession. Methods Using individual and aggregate level data collected from 27 EU countries in the Eurobarometer surveys of 2006 and 2010, we examined changes in unemployment rates over this period among individuals with and without mental health problems. Results Following the onset of the recession, the gap in unemployment rates between individuals with and without mental health problems significantly widened (odds ratio: 1.12, 95% confidence interval: 1.03, 1.34). This disparity became even greater for males, and individuals with low levels of education. Individuals with mental health problems living in countries with higher levels of stigmatizing attitudes regarding dangerousness of people with mental illness were more vulnerable to unemployment in 2010, but not 2006. Greater agreement that people with mental health problems have themselves to blame, was associated with lower likelihood of unemployment for individuals with and without mental health problems. Conclusion These findings study suggest that times of economic hardship may intensify social exclusion of people with mental health problems, especially males and individuals with lower education. Interventions to combat economic exclusion and to promote social participation of individuals with mental health problems are even more important during times of economic crisis, and these efforts should target support to the most vulnerable groups.

National trends in long-term use of antidepressant medications: Results from the US National Health and Nutrition Examination Survey

OBJECTIVE To assess the trend in long-term use of antidepressants by persons aged ≥ 18 years, and the correlates of such use, in the United States from 1999 to 2010. METHOD We examined trends in duration of antidepressant use and correlates of long-term use in data from 6 waves of the cross-sectional National Health and Nutrition Examination Survey (N = 35,379), a representative survey of the general population. RESULTS The overall prevalence of antidepressant use increased from 6.5% in 1999-2000 to 10.4% in 2009-2010 (odds ratio [OR] = 1.54; 95% CI, 1.31-1.81; P < .001). This included an increase from 3.0% to 6.9% in long-term use (≥ 24 months; OR = 2.12; 95% CI, 1.75-2.57; P < .001). Medium-term (6 to < 24 months; from 1.3% to 1.6%) and short-term use (< 6 months; from 2.2% to 1.8%) of antidepressants did not change appreciably in this period. The increasing trend in long-term antidepressant use was limited to adults who received their care from general medical providers (adjusted OR = 3.86; 95% CI, 2.57-5.80; P < .001). CONCLUSIONS From 1999 to 2010, there was a marked increase in long-term use of antidepressant medications in the United States, explaining the overall increasing trend in antidepressant use. This trend calls for greater vigilance in prescribing antidepressants for long periods of time.

Unmet Need for Treatment of Major Depression in the United States

OBJECTIVE This study examined the extent and correlates of perceived unmet need for treatment among individuals with depression in the U.S. general population. METHODS Analyses were based on a representative sample of 6,510 adult participants in the 2005 and 2006 National Surveys on Drug Use and Health who reported a major depressive episode in the past 12 months. RESULTS A total of 3,568 (62.4%) participants had sought mental health treatment in the past 12 months, and 2,942 (37.6%) had not; 34.9% and 26.8% of these groups, respectively, reported unmet need for treatment. In both groups, older age was associated with a lower likelihood of reporting unmet need for treatment, whereas greater distress and impairment and higher education were associated with a greater likelihood of reporting unmet need. Among treatment seekers, treatment from general medical providers was associated with greater likelihood of unmet need, and more outpatient visits and insurance coverage for the full year were associated with a lower likelihood of unmet need. The most common reason for not seeking needed treatment was a concern about costs (cited as a reason by 46.0% of the total sample). CONCLUSIONS Even though rates of treatment seeking have increased, many persons with major depression continue to experience unmet need for treatment, which in this study was mainly attributable to concerns about treatment costs.

Schizophrenia in the Internalizing-Externalizing Framework: A Third Dimension?

BACKGROUND Prior studies of common disorders in community-dwelling adults identified internalizing and externalizing spectra of mental illness. We investigated the placement of schizophrenia and schizotypal personality disorder in this framework and tested the validity of the resulting organization in a clinical population. METHODS The data came from the Suffolk County Mental Health Project cohort (N = 628), which consists of first-admission patients with psychosis recruited from inpatient units throughout Suffolk County, NY (72% response rate). The sample was reassessed multiple times over the following 10 years. Complete diagnostic data were available for 469 participants. Mental health professionals diagnosed 11 target conditions based on semistructured clinical interviews, review of medical records, and reports of significant others. Two validators were included: family history of schizophrenia and 10-year illness course. RESULTS Confirmatory factor analysis revealed that the The Diagnostic and Statistical Manual of Mental Disorders-IV grouping of conditions fit the data poorly. The best alternative classification consisted of three clusters: internalizing, externalizing, and schizophrenic. Both validators supported the coherence and distinctiveness of the schizophrenic cluster. CONCLUSIONS We replicated internalizing and externalizing spectra in a clinical population, identified a schizophrenic spectrum, and provided initial evidence of its validity. These findings suggest that schizotypal personality disorder may be better placed with schizophrenia, antisocial conditions with substance use disorders, and major depression with anxiety disorders.
